West Nile Virus

West Nile virus (WNV) is an infection transmitted to humans and animals by mosquitoes which have fed on infected birds. According to the Centers for Disease Control and Prevention (CDC), between 1999 and 2008, 28,961 confirmed and probable cases of WNV were reported. Though 80 percent of individuals infected with WNV show no symptoms, approximately one in 150 develop severe illness with symptoms including high fever, vision loss, and paralysis. Though there is no vaccine or cure for WNV, it is important for individuals to have an understanding of how best to protect themselves from infection.

Dusk and Dawn – avoid being outdoors during these periods which are when mosquitoes are most active

Dress – wear clothing that limits exposed skin

DEET – use repellents containing DEET (picaridin and oil of lemon eucalyptus are other repellant options)

Drainage – eliminate areas of standing water in which mosquitoes lay eggs.

In addition, dead birds, particularly crows, which display signs of illness should be reported to authorities for proper disposal. As health officials continue to track outbreaks of WNV, individuals can take appropriate measures to limit their risk of infection and keep their community healthy.
